| Short description | Eucalyptus decorticans, Lysicarpus angustifolius +/- Eucalyptus spp., Corymbia spp., Acacia spp. woodland on coarse-grained sedimentary rocks |
| Structure code | Woodland |
| Description | Eucalyptus decorticans predominates forming a distinct but discontinuous canopy (25-30m high). Eucalyptus decorticans usually forms pure stands, however other Eucalyptus spp. often form part of the canopy and may dominate. Other tree species that may be present and/or dominant include Acacia shirleyi, Angophora leiocarpa, Callitris glaucophylla, Eucalyptus apothalassica, Lysicarpus angustifolius, E. exserta, E. fibrosa subsp. nubilis, E. panda, E. tenuipes, Corymbia trachyphloia, and E. virens. On very rocky shallow soils, Eucalyptus bakeri, E. curtisii or E. viridis may occur. Acacia shirleyi is the most frequent tall shrub, although other Acacia spp. May be locally dominant. There is usually a low tree or tall shrub layer dominated by species such as Acacia sparsiflora, A. burrowii, Callitris endlicheri, Allocasuarina inophloia, Acacia spp., Eucalyptus tenuipes, Alphitonia excelsa and Petalostigma pubescens. A low shrub layer is not usually present, however where it occurs Acacia spp. And Dodonaea triangularis usually predominate. The ground layer is sparse to open, and dominated by perennial grasses, usually Aristida spp. Or Arundinella nepalensis. Occurs on crests, scarps and upper slopes of ranges formed from medium to coarse-grained sediments with shallow soils. Not a Wetland. (BVG1M: 12a). Vegetation communities in this regional ecosystem include: 11.10.4a: Eucalyptus crebra, Corymbia aureola, C. clarksoniana and/or Acacia shirleyi woodland. Small areas that occur in conjunction with E. decorticans woodland. Occurs on crests, scarps and upper slopes of ranges formed from medium to coarse-grained sediments with shallow soils. Not a Wetland. (BVG1M: 12a). 11.10.4b: Eucalyptus crebra, Eucalyptus exserta woodland. Small areas that occur in conjunction with E. decorticans woodland. Occurs on undulating terrain and occasionally on ridgetops. Not a Wetland. (BVG1M: 12a). 11.10.4c: Eucalyptus crebra, Corymbia hendersonii woodland. Small areas that occur in conjunction with E. decorticans woodland. Occurs on undulating terrain and occasionally on ridgetops. Not a Wetland. (BVG1M: 12a). 11.10.4d: Flindersia collina +/- Eucalyptus crebra woodland. Occurs on steep hills and dissected plateaus. Not a Wetland. (BVG1M: 12a). |

| Protected areas | Carnarvon NP, Expedition (Limited Depth) NP, Expedition NP, Palmgrove NP (S), Nuga Nuga NP, Chesterton Range NP, Beeron NP, Expedition RR, Kroombit Tops NP, Minerva Hills NP, MacKenzie Island CP |
| Special values | 11.10.4: Habitat for threatened flora species including Acacia islana, Bertya calycina, Calytrix islensis and Eucalyptus beaniana and the near threatened flora species A. pubicosta and Eucalyptus curtisii. |
| Fire management guidelines | INTERVAL: Fire return interval not relevant. INTERVAL_MIN: 100. INTERVAL_MAX: 100. STRATEGY: Manage surrounding country. Burn surrounding country only under conditions of good soil moisture and when plants are actively growing. Will be difficult to burn owing to a lack of ground fuel that normally occurs in this RE. |
| Comments | 11.10.4: Species richness declines in north of bioregion. Many areas have been extensively logged which has resulted in a decrease in the number of trees in the larger size classes which included many important habitat trees. |
